PLOW.

Specification of Letters Patent.

Patented May 22, 1906.

Application filed October 2, 1905. Serial No. 280 987.

To all? whom it may concern.-

Be it known that we, FRED A. HAMILTON and WILLIAM A. LINKER, citizens of the United States, residing at Arlington, in the county of Mecklenburg and State of North Carolina, have invented a new and useful Plow, of which the following is a specification.

This invention relates to plows and it has for its object to provide a tiltable plow-stock of simple and improved construction, together with simple and improved means for adjusting said stock and for retaining it securely at various adjustments, thereby setting the point of the plow at various elevations, so as to enable it to penetrate into the ground to the desired depth.

With these and other ends in view the invention consists in the improved construction and novel arrangement and combination of parts, which will be hereinafter fully described, and particularly pointed out in the claims.

In the accompanying drawings has been illustrated a simple and preferred form of the invention, it being, however, understood that no limitation is necessarily made to the precise structural details therein exhibited, but that changes, alterations, and modifications Within the scope of the invention may be made when desired.

In the drawings, Figure 1 is a side elevation of a plow constructed in accordance with the principles of the invention. Fig. 2 is a rearelevation of the same. Fig. 3 is a perspective detail view of the adjusting-lever and related parts. Fig. 4 is a sectional detail View taken on the plane indicated by the line 4 4 in Fig. 2.

Corresponding parts in the several figures are indicated throughout by similar characters of reference.

Pivotally connected with a beam 1 by means of a transverse pin or bolt 2 is the stock or standard S, which is composed of side members 3 3, spaced apart at their upper ends by the beam and at their lower ends y an interposed block or spacing member 4. The plow-blade 5, which may be a turningplow, as shown in the drawings, or which maybe of any desired construction, is mounted upon the stock or standard by means of a heel-bolt 6, extending through a plate 7,

having side flanges 8, exteriorly engaging the members 3 of the standard and provided with a tightening-nut 9, thus providing for the vertical adjustment of the plow-blade and preventing the side members of the standard from spreading.

The stock or standard is capable of adjustment to various positions by means of an adjusting-lever L, which is made up of two side members 10 10, lying in contact With each other at their upper ends and having divergent lower ends embracing the rear end of the beam and connected pivotally therewith by means of a transverse pin or bolt 11. Between the lower extremities of the side members 10 there is pivoted a link 12 upon a pin or bolt 13, said link being connected pivotally at its opposite end with the stock or standard, between the side members of which the end of said link is inserted, the pivotal'connection being made by a bolt 14. The link 12 thus serves to assist in spacing apart the side members of the plow-stock and to brace and strengthen the latter Upon the plow-beam, near the rear end of the latter, is mounted a segment-rack 15, which is capable of engagement by a lip 16, extending downwardly from a sleeve 17, which is mounted slidably upon the portion of the adjusting-lever which includes the parts of the side members 10, which are placed in contact with each other, said sleeve serving to connect the side members and to prevent them from spreading apart. The sleeve 17 has an upward-extending lug 18, which is connected by a link 19 with a springactuated handle member 20, whereby it ma be moved upon the lever to place the lip 16 into or out of engagement with the rack-segment 15.

As will be seen from the foregoing descrip tion, the lever L may be readily manipulated to adjust the plow-stop to various positions, the parts bein retained at the various adjustments by t 1e lip 16 of the sleeve 17 engaging the rack member 15. This construction is extremely simple, durable, and effective.

The plow has been shown as provided with handles 21 and with handle-braces 22 of ordinary construction, the handles being provided, as is usual, with a spacing device consisting of a rung 23.

Having thus described the invention, what and pivotally connected with the side mern is claimed is- 1 bers of the standard and the lower spaced 1. In a plow, a pivoted stock or standard l ends of the side members of the adjustingcomposed of two members spaced apart, a lever, a sleeve slidable upon the contacting blade supported upon the standard, a plate ortion of the side members of the lever and engaging the rear side of the standard and having a lip engaging the rack segment, having side flanges exteriorly engaging the sprin -actuated handle, and a link connectside members thereof, and a bolt connecting mg said handle with the sleeve. said blade and plate.
